A Study of Ustekinumab in Pediatric Participants With Moderately to Severely Active Crohn's Disease

Study Purpose

The purpose of this study is to evaluate the efficacy of ustekinumab dosing in inducing clinical remission (Global) and in maintaining clinical remission (US); to evaluate the safety profile and ustekinumab exposure (pharmacokinetics [PK]) in pediatric participants with moderately to severely active Crohn's disease.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	2 Years - 17 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Have Crohn's disease or fistulizing Crohn's disease with active colitis, ileitis, or ileocolitis, confirmed at any time in the past by endoscopy and histology.

- Must have moderately to severely active Crohn's disease (as defined by a baseline Pediatric Crohn's Disease Activity Index [PCDAI] score greater than [>] 30); have ileocolonoscopy with evidence of active Crohn's disease defined as presence of ulceration (which is equal to Simple Endoscopic Score for Crohn's disease [SES-CD] score greater than or equals to [>=] 3) during screening into this study.

The ileocolonoscopy procedure must occur within approximately 3 weeks prior to the administration of study intervention at Week 0 (Induction Period). A video ileocolonoscopy recorded within 3 months prior to the Week 0 (Induction Period) visit may be used in case of rescreening of a participant who had an ileocolonoscopy but failed the initial screening for another reason, on a case-by-case basis, after consultation with the sponsor. If unable to evaluate ulceration due to stricture or inadequate bowel preparation, at least one of the following criteria may instead be applied: an abnormal C-reactive protein (CRP) (> 0.3 milligram per deciliter [mg/dL] or 3.0 milligram per liter [mg/L] at screening) or; fecal calprotectin of >= 250 milligram per kilogram [mg/kg] or >= 250 microgram per gram [mcg/g] at screening.

- If receiving enteral nutrition, must have been on a stable regimen for at least 2 weeks prior to induction week 0 (Week I-0) - Females of childbearing potential must have a negative highly sensitive urine pregnancy test at screening and at Week I-0 prior to study intervention administration.

Exclusion Criteria:

- Has complications of Crohn's disease such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestation that might be anticipated to require surgery, that could preclude the use of the PCDAI to assess response to therapy or would possibly confound the ability to assess the effect of treatment with ustekinumab.

- Have a history of latent or active granulomatous infection, histoplasmosis, or coccidioidomycosis, or have had a nontuberculous mycobacterial infection prior to screening.

- Presence or history of any malignancy including presence or history of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (example, nodes in the posterior triangle of the neck, infraclavicular, epitrochlear, or periaortic areas), and monoclonal gammopathy of undetermined significance, or clinically significant hepatomegaly or splenomegaly.

- Have a history of moderate or severe progressive or uncontrolled liver or renal insufficiency; or significant cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic, psychiatric (including suicidality), or metabolic disturbances.

- Received an investigational intervention including any investigational vaccines or used an invasive investigational medical device within 3 months before the planned first dose of study intervention or is currently enrolled in an investigational study; receipt of an investigational vaccine for Coronavirus Disease 2019 (COVID-19) is not an automatic exclusion criterion

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04673357
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3

Arms & Interventions

Arms

Experimental: Open- Label Ustekinumab Intravenous (IV): Induction Period

All participants will receive a single IV administration of ustekinumab at induction Week 0 (I-0) based on body surface area (BSA) (milligram per meter square [mg/m^2]) or weight-tiered induction dose (milligram per kilogram [mg/kg]).

Experimental: Ustekinumab Subcutaneous (SC) Every 8 Weeks (q8w): Maintenance Period

Participants will receive SC administration of ustekinumab q8w based on BSA (mg/m^2) or weight-tiered induction dose (mg/kg) at maintenance weeks (Weeks M)-0, M-8, M-16, M-24, M 32, and M-40 and matching placebo at Weeks M-12 and M-36 to maintain the blind.

Experimental: Ustekinumab SC Every 12 Weeks (q12w): Maintenance Period

Participants will receive SC administration of ustekinumab q12w based on BSA (mg/m^2) or weight-tiered induction dose (mg/kg) at Weeks M-0, M-12, M-24, M-36 and matching placebo at Weeks M-8, M-16, M-32, and M-40 to maintain the blind.
